Honestly, I've played video games my entire life and I've played all manner of puzzles, adventures, RPG's, strategies, MMO's, and on every freaking platform (pc, console, handheld), and I have NEVER had such a hard time fighting a boss than I did with Demise at the end of SS. I just... I couldn't even! It was pathetic! I could not get that fight right despite attempt after attempt, and honestly I gave up and threw the controller at my husband and had him do it xD. I haven't defeated Demise on my own and a portion of it just pisses me right off, haha. I've not even attempted the Boss Rush because I thought Demise would be in it, even though now I know that's only on Hero Mode. Oh well.
